The main object of the present invention is to It will be seen that when it is desired to change provide an arrangement which will enable a over from printing in black to printing in another printing machine which is designed normally to color, red, for example, it is merely necessary to 5 print in one color, usually black, to be adapted render inoperative the existing black ink supply cheaply and easily to print in some other color for the selected cylinder and to locate the transor colors. portable nk rail 5 and associated parts in feed- According to the present invention there is proing position whereupon red ink will be supplied. 15 vided an ink feeding device which is movable so The arrangement may be such that the whole 10 that it can be located in ink feeding position with vddth of the cylinder to be inked is fed with color, respect to the usual ink distribution system of but obviousiy color may be fed to selected parts any printing couple of a printing machine or with of the cylinder (e. g. different page sections) respect to any page section of the distribution either by employing aiull length ink rail as shown system. For example, if the painting machine in Figure l and renderin inoperative different 15 be designed normally to print in black and it be sections as is required by rendering inoperative desired to print on one page say in red, the transthe corresponding individual pumps, or by the portable feeding device would be supplied with use of a short transportable ink rail and its assored ink and would be placed in feeding position ciated parts which can be located in difierent 29 with respect to the distribution system or section positions corresponding to different page sections thereof corresponding to that page. of the printing cylinder, the pumps for the exist- The invention is illustrated in the accompanying ink rail b ing correspondingly and similarly ing drawing in which retained operative for use.

ing cylinder. I can in the latter case be arranged to replace a The drive to the pumps in the pump box is efsection of the ink rail feed as has been described fected through a flexible shaft 8 which may be in connection with a transportable ink pump by 55 providing a stretcher on the frame of the present invention on which the portable fountain and its lifting roller can be placed and slid to any described position corresponding to different sections of the printing cylinder.

It will be seen that with the transportable ink feeding mechanism of the present invention a printing machine can readily be adapted to print some color other than that for which it is normally equipped and that such adaptation can easily and cheaply be eiiected.

It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired the present em.

bodiment be considered in all respects as illustrative and not restrictive, reference being had to the app-ended claims rather than to the foregoing description to indicate the scope of the invention.

What I claim is:

i. In an inking mechanism for printing machines having printing couples and ink supplying source therefor, a portable ink reservoir, and means operably interposed between the reservoir and a selected printing couple for forcibly supplying a film of ink to the selected'printing couple independently of the said ink supplying source.

2. In an inking mechanism for printing machines, a portable ink supplying unit including an ink reservoir, an ink rail, means for subjecting the ink reservoir to fluid pressure, ink pumps operably interposed between the reservoir and the ink rail, the ink rail being constructed and arranged to supply ink to the ink cylinder of a printing couple of the printing machine.

3. In an inking mechanism for printing machines, a portable ink supplying unit, including an ink reservoir, an ink rail, ink pumps operably interposed between the reservoir and the ink rail, flexible means interposed between a driven member of the printing machine and the ink pumps for driving the pumps, the ink rail being constructed and arranged to supply ink to the ink cylinder of a printing couple of the printing machine.

4. In an inking mechanism for printing machines, a portable ink supplying unit including an ink reservoir, an ink rail, ink pumps operably communicating with the ink rail, a conduit communicating the ink reservoir With'the ink pumps, means for driving the pumps from a driven member of the printing machine, means for subjecting the ink reservoir to fluid pressure, the ink rail being constructed and arranged to supply ink to a printing couple of the printing ma.- chine. V

5. In an inking mechanism for printing machines, a portable ink reservoir, portable means for subjecting the ink reservoir to fluid pressure, an ink rail, ink pumps operably'interposed between the reservoir and the ink rail, the ink rail being constructed and arranged to convey ink to the ink cylinder of a printing couple of the printing machine.

6. In an inking mechanism for printing machines having a source of ink supply, a portable ink reservoir, an ink rail, ink pumps, a conduit 7 7. In an inking mechanismfor use in printing machines having printing couples and ink supplying source therefor, a portable ink supplying unit including an ink reservoir independent of the said ink supplying source, an ink rail, ink pumps operably interposed between the reservoir and the ink rail, the ink rail being constructed and arranged to supply ink to the ink cylinder of a printing couple of the printing machine.

8. In an inking mechanism for use in printing machines having printing couples, ink supplying source and inking apparatus, a portable ink reservoir independent of the ink supplying source, an ink rail, ink pumps operably interposed between the reservoir and the ink rail, the ink rail being constructed and arranged to convey ink to an ink cylinder of the printing couple.
